our price £4,250.00

The Dakota BT2-DL Ultrasonic Bolt Tension Monitor incorporates all of the great features of the BT1-DL unit, with some added benefits in terms of features, hardware, speed, and length. The BT2-DL very accurately measures fasteners up to 100 feet in length.

The Dakota BT1-DL and BT2-DL

Ultrasonic Bolt Tension Monitors define the state of the art in the measurement of the actual elongation produced by tightening a threaded fastener. They can very accurately measure the elongation of fasteners of most material types. The measurement is achieved by determining the change in the transit time of an ultrasonic wave along the length of the fastener as the fastener is tightened. The on-board microcomputer automatically interprets this time measurement to display the time (nanoseconds), elongation, load, stress, or % strain from stretching a fastener.
